For the chronology of revision to operating hours for full day bus services introduced after 1 Jan 2000, refer to this article.

The operating hours for public bus services in Singapore are frequently reviewed by the Land Transport Authority (LTA). These revisions to operating hours often occur in tandem with route amendments to bus services, as well changes to last train timings at MRT stations (for residential feeder bus services), or simply due to evolving passenger demands on bus services over the years.

This article provides a chronology of revisions to operating hours for full day public bus services in Singapore introduced before 1 Jan 2000. As the operating hours for peak hour one-directional bus services are calculated based on the number of trips operated instead, they will be excluded from this article.

Excluded Bus Services:

Bus Services 20, 177, 981
Express Bus Services ~~507~~, ~~508~~, ~~520~~

Full Day Bus Services introduced before 1 Jan 2000
